I'm still all fucking YEEE-EEEE-EEEEAH about Guitar Hero. I beat it on medium and hard, and I've beat all but two songs (Cowboys from Hell and Bark at the Moon) on expert. Expert mode is actually really fun, and maybe even a little easier in some ways than hard, because you play pretty much all the notes. So, if you know the tune well, then there's not a lot of guesswork on the timing. I think the only reason I can't get past these last two is that my arms just give out after a while from sheer exhaustion. I'll get them though. I can get through about 91% of CFH and 60% of BATM.
I unlocked the "Grim Ripper" and sometimes end up blowing a song because I get distracted watching is awesome on-stage antics.
